There are ______ main effects in a 3 × 4 ANOVA design.

A researcher obtains SSX= 32.75, SSY = 155.75, and SP = 44.76 for a set of n = 4 pairs of scores. Calculate Pearson correlation (r) for these scores.

PART I (Q1 – Q25): ANOVA

An experiment is conducted to compare the enthusiasm of participants with two different personality types (Type A, Type B) performing five different tasks. Complete the ANOVA table for this experiment: Source Sums of Squares degrees of freedom       Mean Square          F       p Task     10.5           4           2.63       3.75   0.045 Personality       A           1             C        25   0.001 Task x Personality       1.5           4             D       0.54   0.887 Error      45.5           B           .70                Total       75          99 Type your answers below and round to 2 decimal places A = [A] B = [B] C = [C] D = [D]

Using a 2X2 between subjects ANOVA, a researcher seeks to examine mean mental health scores in academia by people’s roles (student or faculty) and gender (male or female).  Mental health scores (DV) are listed below. Male (B1) Female (B2) Students (A1) 5 5 Faculty  (A2) 8 8                                                   Use the given information to determine if there is a main effect and/or a interaction. MB1 = 6.5, MB2 = 6.5 MA1 = 5, MA2 = 8 Answer the following questions:  1.  Is there a main effect of Role? [yes] 2. Is there a main effect of Gender?  [no] 3. Is there an interaction?  [no1]

A researcher reports that the mean difference in the body weight of rats following a pharmacological treatment versus control is 10 g, with a pooled sample variance of 345. Calculate the Cohen’s d (round to 2 decimal places)

Aerosmith Corporation issued $15,000,000, 7%, 20-year bonds to yield 8% on January 1, 2024. Interest is paid on June 30 and December 31. The proceeds from the bonds are $13,515,542. If the effective-interest method of amortization is used, what amount of interest expense will be recognized in 2024? (Select the closest answer.)

An analysis of variances produces df total  = 33 and df within = 30. For this analysis, how many treatment conditions are being compared?

A research wants to determine the correlation between gender (male, female, other) and political party (democrat, republican, other). What type of correlation coefficient should the researcher conduct?
